Maplins are doing a cheap deal: £10 for a digital thermometer

I guess the battery in the transmitting sensor will go before the one
in the receiver.
Does anyone know how long will it be before that happens?
The manual claims 12 months for the main unit and 6 months for the remote
sensor. I think I've had mine running longer than this.
Although the remote unit probably has a higher current drain than the
receiver it conserves power by only transmitting brief pulses every 30
seconds or when the temperature changes by more than 0.2C.
Unless they've changed the design, the remote unit uses 2 AAA cells and
not 3 as stated on the web page.

have one of these as well, both units take 2 AAA cells and the main unit
has a low battery indicator for the outdoor sensor. The main unit is silver
and not white as shown in the picture. I have had mine since january and the
outdoor sensor still going strong.
